Be it known that I, .DoMENIooBoriu'rro, a citizen of the United States, residing at Roanoke; in the county. of XVdodfordf-and State of'Illinois, have invented certain new and useful Improvements infFlui'd-Motor Systems, of which the following is a specification, reference being had therein-to the accompanying drawing.

This inventionrelates to apparatus for in motion, and relates more particularly'to means for collecting and condensing the fluid so as to increase. its velocity at the points where it passes the moto'r element of the mechanism." 1 1 One object of the invention is to. provide an apparatus whosecom'ponent parts are so which. all of the parts are mounted in one compactstructnre ,sothat the resistance to: the flow: of the. fluid 'willbe' re chicedfto a mini1num..

positioned and related thatjffrom a fluid passing a certain regiona volume canfbe collected and condensed; and, while so col- .lected and condensedican be utilized to furnish power. I A

'Another object of the invent on is to provide an apparatus of .theabove class in In 'my co-pending application, Serial Number 460,102, filed April 9,1921, Iliave shown and described a fluid motor systems.

in which the. energy is. derived from" the I have illustrated my invention asbeinq applied to mechanisms adapted to air currents; but it will be} understood that I do not limit myself to this particular fluid and that modifications of the structure shown can be madein great many details Without departing from the spirit or scope of the invention. r

In the drawings illustrating a mechanism embodying my improvements a framework is indicated for supportingsome of the parts. i i

This comprises the: uprights, l, suitably 7 secured in firm foundations at theirbasc f and carrying at their upper ends the cross bars 2. 2.. .3 s a circular track firmly sup ported by the uprights .4, tot which. there are fa suitablenumber to give the required fstrength and rigidity. .They' are bolted at 7 their lower endsfto the crossbars 2, as at 5, and attheir upper ends to the bascof the track' rail 3, as at 6.

A central hollow pedestal .7 is also suit ably .imbedded' in I a foundation in the ground and is so positioned that its-vertr.

cal axis isat that-enter of the supporting, framework 1 2." ;Uponthis pedestal" is ro- I tat'ablymounted a hollow 'shaft- 8 rename mg at 1ts lowerend 1n a flange 9 to which 'is secured. a bearing annulus j 10, having aracew'ay 11. The upper endofthepedestal also terminates in a flange-12 which f carries an annulus 13. having a raceway 1 the latter registering with the raceway 11 of the bearing annulus of the; shaft 8. Ballslfi rollingin the raceway provide an anti-friction bearing for the1sl1aft 8 and permit it to rotate freely on the pedestalf,

'Near'the upper end oftheshaftf8 and connected rigidly thereto are two funnels 16and positioned di'ametricallv-oppo- .I

site tofeach' other and having their mouth ends remote froml the shaft. -They'are se jcured to the shaft bynieans of flanges 18. 18 by whi' they canbe bolted or' fiveted' to the shaft. f

Each "of the funnels 1.6" and 17 provided with, a bracket QLrigidly isecurd thereto, each bracket carrying at'itsFI wg-r endv a roller 22 which travels on the" circus la r track 3 when the shaft 8. and tunnels are rotating. v

A-vane2'3 is rigidly secured 4 to the upper. portion of the funnel 17 by means 01' bolts24t which pass'through a flange on the bottom edge oi the vane and thronglrthe shell of. the fiin11el. fTl1e vane 23. is shaped,,:

at'its inner end, to conform to, therertical wall of the shaft Sdand'to extend to'a point approximately at the center of the shaft and across the top thereof. Thevane serves to hold in; place a cap 25 which fits over the upper end ofthe shaft and to which the vane flange is bolted as at 26.

p In the interior of theshaft 8 ismounted an air motor comprising the spoon-shaped blades 27, 27 which are secured to a hub 28, the latter, in turn, being keycd tor a vertical shaft 29 which extends 'approxt @mately the entire distance from the top of the wallet the shaft and the latter to l I ment by collars i-llasecured to the shaft by of the shaf to the base of the pedestal.

The shaft 29 is he'ld against lateral move ment by bearing plates and 31, the former bcing'secured to the inner face the inner ."ace of the wall of the pedestal. r I a a 7 u I he shaft 18 also held against vertical movepi ns, there being vone of these collars above each bearing plate to prevent movement 1 v V V V ownward and one below each bearing plate to prevent movement upward.

The-chamber in which the .air motor is located is made air-tight from the other parts of the shaft 8 by means of horizontal plates '32, one above and one below the motonand which are bolted to the wall of the shaft as shown at '33. The bolts 33 as shown also serve to secure the flanges 18 at the inner ends of thefunnelsto the shaft .8. To assist in directing the air against the blades Wot/the air 'motor, the throatway of the funnel 16"is shaped, at one side, asshown at 34c- And the side wall of the [aperture in the shaft is correspondingly curved as shown at .36. And similarly one of the sidewalls of the aperture; 37. in the 1 shaft and the throatway of thefunnell'? are formedto assist in directing the air from the motor chamberand into the discharge funnel 17.

"The method of using 'my improved apparatus will be readily understood from the I foregoing description and from the draw- 3 tion. The'vane 23," when ings. o

' The'entire structure preferably mounted onv the summit of a topographical elevaany wind is blowing, will cause the rotatable parts of the structure to swing tosuch position that the mouth of the funnel 16 will face toward the direction from which the windisblowing and the mouth of the funnel 17 will Afte it has expended its energy upon the itace in the opposite direction. The air which is collected in the receiving funnel 1,6 is

rapidly condensedin volume because of the tapering walls and when it passes through the throatway of the funnel its velocity 1s much greater, than that which it originally bad; From the throatway 1t passes through the aperture 35 of the shaft and is directed against the blades 27 of the motor causing, them to rotate, and, dr ve the shaft 29.

blades it is exhausted through the shaft aperture 37 into the throatway of the funnel l7 and thence is exhausted again into the atmosphere. The outside air passing the funnel 17 tends to create a vacuum at points in the vertical transverse plane of the mouth of the funnel and within its outlines, and

this materially aids in exhausting the air from the interior of the funnel and correspondingly increases its velocity as it is discharged.

- That part of the structure which includes the receivin and dischar e' oa'rts and the a b l v air motor is free to swing, as a unitary str.ucture,- as the direction of the'fiow ofair changesand a continuous rotation of the air motor is insured as long as there is any wind Power may be taken from the blowing.

shaft29 in any desired manner such as by gearing or pulley wheels.

What I claim is; 1 1. In an apparatus of the class described the combination with a fluid motor ot selfadjustingmeans immediately adjacent motor to properly receive and discharge the fluid by/which the motor is, adapted to be driven, said means comprising a funnel-- funnel both of saiddeshaped receiving device and; a shaped discharging device, vices being rigidly connected toqcther and positioned to have their enlarged ends face n diametrically opposite direction,

funnel-shaped. discharging device, rollers carried by said casing and engaging the track, a rotary wheel within the casing be- 7 tweenthe endsof the funnel-shaped devices, withits axis coinciding with that of the tubular upright, and'a power shaft connected to the wheel. i

In testimony whereof. I ailix my signature.
